To ALL WHOMIT MAY ooNoERN':

Be 'it known that I, JOHN A.

Similar letters of`lrefeience indicate like parts.

e accompanying drawigyand to O O is the vault, the walls of which maybe constructed of stone, brick, or other .suitable material, into,v

which the gate is depressediwhen open for the passage' of vehicles, sai-d vault being-ofA suitable length, width, and depth to accommodate the gate and its.equipments,'and to allow free access to the same for the purpose'of making necessary repairs. CA is a weight, for 'the purpose of assisting in raising or closing the gate B. D is a leveifantuatedbythe ooi-ds'ele, for the purposeoi" closing thegate, said lever vbeing' pivoted to the Abottom bar of the gate, equidistant from the ends,`and to the right-hand post A. E E are pulleys used in operating i the lever D by the said cords e e. b'bis aspring-latch for holding the gate in position when closed. ff are cords used to operate the spring-latch b b, by releasing which the' gate is' permitted or caused to open of its. own gravity. A A are the posts of the gate, havingtracks a a onI the inner surface,ion,wliich the ,pulleys at each `corner o f the gate traverse freely in opening and closing. The gate is opened by actuating the cord f, and closed by operating the cord e, said cords passing over pulleys H H attached tothe .posts GG. I 'P is a platform covering the vault, andV formingl the roadway, in whicha suitable opening is provided, through which the vertical rods, of which the. gate is formed, work freely in opening and closing. Said 'platform may be supported by suitable girders of iron or wood, the top surfare of said platform being made suiiciently conveii, s'o as to shed water ox` sleet, and prevent it from going into the vault. The top` bar of the gate being wide enough to close jle opening' in -the platform, thus preventing the ingress'lof dirtin' the passage of-vhioles or animals.
